How to use spring boot making a common library

Spring Lemon would be a good example for this. It uses Spring Boot, and is meant to be included in other Spring Boot applications. This is what we did to create it:

1. Created a Spring Boot application, using the Spring Boot Starter Wizard of STS.
2. Removed the generated application and test class.
3. Removed spring-boot-maven-plugin, i.e. the build and the pluginRepositories sections in pom.xml. (See how a pom.xml would look without these sections).
